Disappearance of a Thread

Body: 

Quite recently there was a post here regarding somebody whose elderly mother had both prolapse and dementia. It seems to have disappeared. While I was not the person who posted the original question on this theme, I was one of the people who posted a comment.

So was wondering as to how this particular thread was deleted and why? If we knew the answer as to the reason for it's deletion, then perhaps we will know what NOT to post in the future

Sevilla, the thread was automatically deleted when the user who started the thread was deleted. And the reason that user was deleted is that she was using our forum as free advertising for a product she makes and sells. - Surviving

Thank you for explaining.
